A method of enhancing the dispersibility of alpha-alumina monohydrate wherein there is formed a mixture of an alpha-alumnina monohydrate, water, and a dispersibility enhancer comprising an effective amount of a monobasic acid, a salt selected from the group consisting of salts having the formula MX wherein M is a polyvalent metal cation constituent for which the solubility product KSP of the corresponding metal hydroxide is less than 10-20 and wherein X is an anion constituent derived from a monovalent acid having an ionization constant KA greater than 10+1 and certain phosphorus and antimony chlorides, followed by drying the mixture, without aging, to produce a dried, alpha-alumina monohydrate having advanced water dispersibility. |
